Scotland Yard vowed to track down and arrest protesters who posted "really inflammatory, inaccurate" messages on Facebook, and now it has delivered. Two teenagers appeared in court today in connection with messages posted on Facebook allegedly encouraging people to start rioting.

16-year-old Alexander McQuarrie showed up at Glasgow Sheriff Court today after being arrested on Tuesday afternoon following an operation by Strathclyde Police in Ibrox, Glasgow. He was charged with encouraging others to riot in the city and accused of breaching the peace by creating a Facebook Group.

18-year-old Liam Allan appeared at Dundee Sheriff Court under similar accusations. He was arrested in connection with Facebook posts encouraging others to show up in Dundee city centre with weapons and cause disturbances.

The police is of course still working to identify others who may be inciting people to cause public disorder. The BBC reports social networks are being monitored closely and "decisive action" will be taken to prevent violence.
